The NWE-3GA is the ideal solution for inserting Nielsen Watermarks into the audio for television<br />
programming. The timestamp structured watermarks make use of the “SID” (Source Identifier), which is a<br />
serial number used by Nielsen and the television industry to uniquely identify program content, to ensure<br />
proper crediting of viewing.<br />
The NWE-3GA accepts an SDI input (3 Gb/s, 1.5 Gb/s, or 270 Mb/s) and 4 AES-3id digital audio inputs. It<br />
applies the watermark to up to 16 PCM audio channels selected from the 16 embedded and 8 AES channels.<br />
Embedded audio signals that are watermarked are re-embedded into the same location in the SDI output.<br />
AES audio signals that are watermarked are re-encoded into the same AES output.<br />
The module can be configured to support a variety of audio configurations, from a single stereo pair up to two<br />
5.1 surround groups plus two stereo pairs.<br />
The NWE-3GA includes a video frame delay to ensure proper audio-video synchronization. The companion<br />
rear connector module provides relay bypass of the video and AES signals, allowing the NWE-3GA module to<br />
be inserted or extracted without interrupting the program path.<br />
The timestamp included in the watermark data can be synchronized to either SMPTE 12M LTC (both<br />
balanced and unbalanced inputs are provided) or network time obtained by the frame from an NTP server.<br />
